KNOTTING DEVICE FOR CFtAlN-BINDERS(A SPECIFICATION forming part of Letters Patent No. 415,756, dated November 26, 1889.

i `Application filed October 13, 1886. Serial No. 216,090. (No model.) Y

To a/ZZ whom it may concern:

Be it known that we, IVILLIAM N. IVHITE- LEY and WILLIAM BAYLEY, citizens of the United States, residing at- Springtield, in the i county of Clark and State of Ohio, have in- I to those constructed upon the general prin! ciples set forth in Letters Patent No. 212,420, granted February 18, 1879, to J. F. Appleby, and is in the nature of improvements thereon.

The objects of our invention are to simplify the mechanism by which the cord-holder disk is actuated and at the same time to obviate certain defects in the operation of the knotting devices used upon the, class of grainbinders to which our invention is applicable, and to so construct and arrange the parts by which the cord-holder disk is actuated that its movements may rotate it promptly and positively when required and hold it securely at rest at all other times. These objects are accomplished by means of the mechanism shown in the accompanying drawings and hereinafter described.

In the drawings, Figure l is a perspective View of such parts of a knotter7 as are necessary to clearly illustrate our invention. Fig. 2 is a vertical section of the saine with some of the parts shown in elevation. Fig. 3 is a side elevation of the cord-holder and cordholder disk, and Fig. 4 is a longitudinal section of a modification of the method of piv oting the swinging frame to the main frame.

Similar letters refer to like parts in the several views. l

A is the k11otterfran1e, having formed on it two horizontally-perforated lugs or projections c o, to which the swinging cord-holder frame B is pivoted by the shaft E, which transmits power from the tyer-wheel O to the cord-holder diskK. The binder-shaft m and tyer-wheel C are arranged as usual, the latter being provided, however, with a segment of an internal gear having formed thereon the teeth c, which engage those of the Inu-.

tilated pinion D, which is provided with two fiat spaces d d, which lit the inner surface of the delay-rim g. The number of teeth c and of teeth on each side of the pinion D are the same, whereby the pinion D In'akes only one'- half of a revolution to one revolution of the tyer-wheel, the lugs 7L 71., formed upon pinion D, being engaged by the pin p, fixed in the delay-rim c, for' starting the pinion D positively and causing the teeth to properly engage in the usual manner in suoli cases.

Upon the shaft .E is fixed the bevel-pinion F, engaging the bevel-wheel G, which is iixed to the shaft M, journaled in the swinging g cord-holder frame B and having fixed to its lower end the bevel-pinion H, which engages the bevel-pinion '1*,iixed to the shaft J, jour'- vnaled in the swinging frame B and having fixed to its front end the cord-holder disk K.

The cord-holder disk K has six cordenotches formed therein,and must be so actuated that one of the notches shall arrive at ,the cordholder L at each knot formed. To accolnplish this the pinion D is caused to make onehalf of a revolution to every revolution of the tyer-wheel. The bevel-pinion F has Vone-v third as many teeth as the bevel-wheel G. Consequently the shaft M makes one revolution to six revolutions of the tyer-wheel, and, the bevel-pinions H Tbeing of equal diameters, the cord-holder disk K rotatesone-sixth of a revolution, or from one cord-notch to the next, at each revolution of the tyer-Wheel.

The cord-holder L is of the usual construction, and is pivoted to the swinging frame kB at Z and held in place, as usual, by the spring N, attached to the projection b of the swinging f rame B.

The cord-holder and cord-holder disk are shown in detail at Fig. 3.

The bill-hook Ris of the usual construction, and has lixed to it the bill-hook pinion fr', which engages the, teeth j of the tyerwheel, by which it is rotated in the usual manner.

The cord-holding apparatus is mounted upon the swinging frame B for the purpose IOO of allowing the cord-holder to swing up to the bill-hook whlethe latter rotates, in order to supply slack cord for properly forming the knot. To accomplish this the swinging frame L has formed on it the arm e, which carries the friction-roller f, which engages the cam P, formed on the tyer-wheel, and by which the cord-holdingapparatus is caused to swing backward away from the bill-hook, and by a depression in said cam the swinging frame B is allowed to swing inward toward the billhook R, as described. NVhen -the swinging frame B is caused to swing outward by the actionof the cam P, it is arrested at the proper point by the stop-lug b2, formed upon it, coming in contact with the frame A at a2.

The cam P mayv be constructed of two tracks or rims, the friction-roller f being situated between them, thus insuring a positive vswinging motion to the cord-holding apparatus; but in practice it is found that the pullingof thecord as the bill-hook rotates in formingA the knot is quite sufficient, and a much more natural movement in cases where thecord Varies much in the size, the.

ln Figs. l and 2 we have shown the swinging frame B pivoted to the lugs a a of the main frame A by the shaft E; but it may be preferable to form the bearing for the swingingy frame B upon projecting sleeves formed upon the lugs c a, as shown in Fig. et, and confined thereon by a nut V or other similar means. The shaft E passing through the stationary lugs a a is not then interfered with or cramped bymthe swinging frame B.

The Operation of our invention is as follows, viz: The needle-arm S, encircling the gavel vwith the binding-cord, lays the latter overy the bill-hook and into one of the notches It of the cord-holder disk, as shown. The tyer-wheel then rotating in direction of the arrow, the teeth c, formed thereon, engage those of the pinion D,which, operating through the shaft E, gears F G, shaft M, and gears H T, rotate the cord-holder disk K one notch, thus forcing the cord down to the position of the notch k2, Fig. 3, at which time the teeth c of the tyer-wheel and those of the pinion D disengage, and the delay-rim g coming in contact with one of the flat surfaces Cl of the .pinion D the latter is locked and consedepression in the cam P comes opposite the friction-roller fof the arm e, and the cordholding apparatus is allowed by the pulling of the binding-cord to swing inward toward the bill-hook to the position shown by dotted lines in Fig. 2, thus furnishing slack cord for the formation of the knot, after which the'cord being severed by any convenient device the cam P causes the swinging frame by the stop-lu g b2 coming in contact with the frame A at d2.

Ve are aware that knotters have heretofore been constructed in which the cordholder disk was actuated by means of spur and bevel gears transmitting the power from the tyer-.wheel or binder-shaft, but in all such cases the cord-holder disk was A journaled to the main frame or some fixed part thereof; but in our invention we have so constructed the parts that the cord-holder and cord-holder disk may be mounted upon a swinging frame, the said frame swinging forward for the purpose of furnishing slack cord to the bill-hook in forming the knot, as in practice this feature has been found necessary to prevent too great a strain on the cord, which frequently caused the accidental breaking thereof.

Having thus described the nature, objects, construction, and use of our invention and point-ed our wherein it differs from the usual forms now made, what we claim as new, and desire to secure by Letters Patent, is-

In a knotting device for a grain-binder, the combination of a Xed frame having the knotting-hook journaled therein, a wheel `on the tyer-wheel shaft, provided with a segmentgear c, a shaft E, journaled in brackets on said fixed frame and provided with a spurgear D in mesh with said segment-gear and a bevel-gear F, a swinging frame pivoted on said shaft E, a rotary cord-holder having a bevelgear, countershaft-connection with said gear F, mounted. on said swinging frame, and automatic means to swing said swinging frame on its axis coincident with the axis of the driving-shaft E.
